[0002] Modern architecture features increasingly complex designs, and zigzag curtain walls have become very popular in recent years. Horizontal zigzag curtain walls are a common type, but conventional horizontal zigzag curtain walls require multiple adapters to achieve, making installation relatively complex. The positioning of the keel is difficult, and the amount of high-altitude welding is also large. In order to ensure installation accuracy and appearance quality, the construction period is usually relatively long, which is not conducive to rapid construction and green construction. Utility Model Content

[0003] The purpose of this utility model is to provide a prefabricated horizontal zigzag curtain wall structure to solve the problems mentioned in the background art. This utility model is achieved through the following technical solution:

[0004] A prefabricated horizontal zigzag curtain wall structure includes: embedded parts installed on the main body of the building, groove-type adapters welded to the embedded parts, and multiple sets of horizontally and vertically arranged keel units; the groove-type adapters are provided with through holes penetrating the two side groove walls; each set of keel units includes a main keel and a secondary keel that form an L-shape in the horizontal plane after assembly, and a first vertical square tube is provided at the connection between the main keel and the secondary keel. The extension direction of the first vertical square tube is perpendicular to the horizontal plane where the main keel and the secondary keel are located. One end of the main keel and one end of the secondary keel are respectively welded to two adjacent facades of the first vertical square tube; the other end of the main keel is connected to a second vertical square tube. The first vertical square tube is parallel to the second vertical square tube. In the lateral extension direction, the second vertical square tube and the secondary keel are connected by angle steel to achieve lateral connection between two adjacent keel units. In the vertical extension direction, the two adjacent keel units are connected by steel inserts that pass through the inner cavity of the second vertical square tube. The second vertical square tube and the steel insert are provided with lateral through holes. The steel insert and the second vertical square tube are fixedly connected by bolts passing through the through holes. The lower end of the second vertical square tube of the upper keel unit is fitted onto the exposed steel insert at the upper end of the lower keel unit. The uppermost keel unit is connected by bolts and slotted adapters.

[0005] Further optimization involves using hot-dip galvanized steel sheets for the embedded parts and hot-dip galvanized channel steel for the trough-type adapters.

[0006] Further optimization involves using hot-dip galvanized square tubing for both the main and secondary keels.

[0007] Further optimization involves connecting the first vertical square tubes of two adjacent sets of keel units in the vertical extension direction, but without any connecting parts for fixation.

[0008] Further optimization involves welding one side of the angle steel to the outer wall of the second vertical square tube of a set of keel units in the lateral extension direction, and welding or bolting the other side of the angle steel to the secondary keel of the next set of keel units.

[0009] Furthermore, the main keel is provided with insulation cotton on the outside, the outermost layer of the main keel is provided with a backing board and glass, and the outer side of the secondary keel is provided with a decorative aluminum plate.

[0010] Furthermore, the glass and decorative aluminum panels are connected end to end to form a closed curtain wall decorative surface.

[0011] The advantages and beneficial effects of this utility model are:

[0012] This invention can solve the problems of high-altitude welding, low installation efficiency, and difficulty in keel positioning in conventional construction and installation methods for horizontal zigzag curtain wall systems, thereby ensuring the installation accuracy and appearance quality of the zigzag curtain wall and greatly improving construction efficiency.

[0013] This invention reduces the amount of welding work on construction sites, which is conducive to promoting non-electrical construction, prefabricated construction, green construction and rapid construction. Attached Figure Description

One end of the main keel 41 and one end of the secondary keel 42 are respectively welded to two adjacent surfaces of the first vertical square tube 43. The other end of the main keel 41 is welded to a second vertical square tube 44, which is parallel to the first vertical square tube 43.

[0025] like Figure 1 , 5 As shown, in the lateral extension direction, adjacent sets of keel units 4 are connected laterally by angle steel 45 to the second vertical square tube 44 and the secondary keel 42. One face of the angle steel 45 in the lateral extension direction is welded to the outer wall of the second vertical square tube 44 of one set of keel units 4. The other face of the angle steel 45 is welded or bolted to the secondary keel 42 of the next set of keel units 4. In this embodiment, welding is chosen. However, for easier disassembly and assembly, a through hole can be provided on one face of the angle steel, and it can also be bolted to the secondary keel of the next set of keel units.

[0026] like Figure 4 As shown, in the vertical extension direction, adjacent sets of keel units 4 are vertically connected by steel inserts 46 that pass through the inner cavity of the second vertical square tube 44. Both the second vertical square tube 44 and the steel insert 46 are provided with transverse through holes. The steel insert 46 and the second vertical square tube 44 are fixedly connected by bolts 3 passing through the through holes. The lower end of the second vertical square tube 44 of the upper set of keel units 4 is fitted onto the exposed steel insert 46 at the upper end of the lower set of keel units 4. In the vertical extension direction, the first vertical square tubes 43 of adjacent sets of keel units 4 are connected but not fixed by any connecting parts.

[0027] The second vertical square tube 44 in the uppermost keel unit 4 is inserted into the slot of the slotted adapter 2. A steel core 46 is inserted into the second vertical square tube 44. The steel core 46, the second vertical square tube 44 and the slotted adapter 2 are fixedly connected by bolts 3 passing through the through hole.

[0028] In this embodiment, the embedded part 1 is a hot-dip galvanized steel plate, and the channel-type adapter 2 is a hot-dip galvanized channel steel. The two are combined into one piece by welding on site. The main keel 41 and the secondary keel 42 are both hot-dip galvanized square tubes, the first vertical square tube 43 and the second vertical square tube are also hot-dip galvanized square tubes, the angle steel 45 is hot-dip galvanized angle steel, and the steel insert 46 is a hot-dip galvanized steel insert. The above five materials are combined into one piece by welding on the ground on site.

[0029] like Figure 1 As shown, the main keel 41 is equipped with thermal insulation cotton 5 on the outside, and the outermost layer of the main keel 41 is equipped with a backing board 7 and glass 8. The secondary keel 42 is equipped with a decorative aluminum plate 6 on the outside. The glass 8 and the decorative aluminum plate 6 are connected end to end to form a closed curtain wall decorative surface.

[0030] In this embodiment, the embedded parts are accurately placed and fixed according to the curtain wall axis in the early stage, and the embedded parts are welded and processed into a whole with the groove-type adapter. After the main and secondary keels of the horizontal zigzag curtain wall system are processed on the ground, they are placed in sequence.
